[VirtualInput] Stop updating the camera angle if window is inactive

Fixes a tiny annoyance during development.
If you have "pauseOnLostFocus" disabled and hat if you Tab out of the game and move your cursor,
the camera would still follow your mouse. If you wanted to copy something from ingame,
your cursor would move constantly, making it very annoying
